Popularized by the internet comic, Cyanide and Happiness, the prankster removes the doorknob to the victims' room when they are asleep. After the knob is removed, the prankster sticks their dick in the hole and knocks on the door to wake the victim up. After the victim tries to open the door, mass chaos will ensue.

Directly from the Cyanide and Happiness comic:

-Dude I totally dick knobbed Dereck last night!
-Hah! He touched your dick.
-I even had an erection at the time.

The Kickstand Effect often happens in the middle of the night. When still groggy from just waking up, males will often turn over to their other side. Not realizing they have morning wood from just waking up, their penis will get in the way and bend, causing extreme discomfort.

When army eating, one shovels food into their mouth as fast as they can, sometimes chewing once or twice before swallowing, so they can be done earlier than everyone else, so they can tend to other more fun activities. This often happens in the army, hence "army eat". When army eating, it takes an average of 3-4 minutes to eat a regular meal.

Dude, the sarge wants us out training in 5 minutes! We'd better army eat!
